I designed this as a companion builds as it’s main focus is debuffing enemies and doesn’t really have much in the way of skills to serve as a useful party face. Plus Shadowheart is right there begging for an MVP build. It’s even lore-friendly depending on your choices.

As stated above this build is all about inflicting the maximum number of Radiating Orb debuffs as possible, and thanks to the combination of Luminous Armor, Callous Glow Ring, and Light Cleric you can apply a ton of them. With good positioning and enough enemies you can apply 10+ per round. Now what does Radiating Orb do? It applies a -1 per round remaining to the afflicted creature’s attack rolls. A -10 to -20 on attack rolls effectively means that enemies can’t hit your party without a Natural 20 and with Warding Flare that not really gonna happen.

A typical first round is to run into the largest clump of enemies and cast Spirit Guardians with your highest spell slot available, then run around until you have hit all of the enemies you can reach. Subsequent rounds will see you using your Channel Divinity, casting Fireball (this will proc the Luminous Armor too thanks to the Callous Glow Ring), or making melee attacks to boost your Spell Save DC; all the while running around to all the enemies you can to trigger Spirit Guardians.

The Elixir of Battlemage’s Power is super useful on this build as it’s a +3 to your Spell Save DC and you can boost it further the Helmet of Arcane Acuity all the while making melee attacks. But early on you will probably want to use Elixirs of Hill Giant Strength combined with the Shining Staver-of-Skulls until you get the Callous Glow Ring.
